FILE FOR CORRESPONDENCE AND THE LIKE.

Specification of Letters Patent. Patented J B 30,1915.

Application filed January 16, 1918. Serial No. 212,038.

To all whom it may concern:

Be it known that I, ERNEST JAooBsEN, a subject of the King of GreatBritain and Ireland, and a resident of the city of Melbourne, in thecounty of Bourke, State of Victoria, Commonwealth of Australia, whosepost-ofiice address is Church Lane, 375 Collins street, in the said cityof Melbourne, have invented certain new and useful Improvements Relatingto Files for Correspondence and the like, of which the following is aspecification.

The object of the invention is to provide a cheap and effective file forexpeditiously bindingcorrespondence and other papers.

By the invention correspondence and the like may be rapidly threadedonto a binding medium and effectively retained in position by a lockingmember, whereby the ends of the binding medium are prevented fromslackening, or becoming loose leading to the damage of the papers. Atthe same time correspondence may be rapidly detached from the file andreplaced as desired.

'The invention may be applied to a cover of the class commonly used infiling systems, or it may be applied to a box or other suitable form offile; For convenience the invention will be hereinafter described andillustrated as applied to a file of the former class, but it is to beunderstood that it is not limited to use therewith.

But in order that this invention may be better understood reference willnow be made to the accompanying drawing which is to be taken as part ofthis specification and read herewith.

Figure 1 is a perspective view of a file embodying the presentinvention.

Fig. 2 is a detail side view on an enlarged scale showing in full linesthe pivoted looking plate closed or in its locking position, the ends ofthe binding medium being shown locked between the locking plate and; themetal reinforcement. In broken lines the locking plate is shown partlyopen or disengaged from the metal reinforcement.

. Parts are broken away for convenience of illustration.

Fig. 3 is a sectional perspective view showing clearly the metalreinforcement attached to one of the leaves Orwings of the cover.

.Parts are broken away for convenience of illustration.

Fig. 4 is a perspective view of portion of the locking plate showing theconverging sides by which the plate may be locked to the reinforcement,and also showing the bot tom edgesof the locking plate as flared tofacllitate the entrance of the reinforcement.

Fig.5 shows the locking plate and reinforcement held together by meansof catches comprising projections. on one element engaging recesses inthe other. A portion of a binding tapeis shown locked in position.

The invention may be applied to a file which includes a cover 2 having acentral crease 3 and side creases t and 5. Hinge ably attached tothecover'2 are opposite leaves or wings 6 and 7, the leaf 6 being adjacentthe side crease 4t and the leaf 7 adjacent the side crease Carried bythe leaf 6 and preferably passing through slits 8. 7

having ends 10 and 11 upon which the correspondence or other paper to befiled is threaded.

Riveted by secured to the opposite leaf 7 is a metal reinforcement 12which is preferably in one on whicheverside of the leaf is deemed ad-'v1sable.

rivets 15 or otherwise suitably therein is a flexible metal binding tape9 Formed in'thereinforcement 12 andalso in the leaf 7 are incuts 13having recesses 1 tto accommodate the ends of the, flexible metalbinding tape 9. The recesses 14 may extend inwardly from the "incuts 18asillustrated or outwardly therefromor in both directions as may bedesired. 7

Pivoted at 17 to the metal reinforcement 12 or to theleaf or wing? is alocking plate or member 16.. This locking plate is also preferablyU-shaped in section. Thelsides or legs of the locking plate 16 may ifdesired, convergeas shown in Fig. 4L in order that the locking plate maymore securely grip the reinforcement and flexible metal binding tape 9.A portion of one of the legs of the locking plate isremoved as at 18 toform an elongated opening which allows the innerside of the lockingplate to clear the binding tape 9. If desired the extremities of theconverging ends of the legs of Catches of any suitable or convenientform may be employed to more effectively retain the locking plate 16upon the reinforcement. These catches may consist of projections 20jutting outwardly from the reinforcement. These projections are adaptedto engage recesses 21 in the locking plate or the projections may beformed on the locking plate and engage recesses in the reinforcement.

The invention is used as follows :The covers 2 are opened and the ends10 and 11 of the flexible metal binding tape 9 bent approximately atright angles to the leaf 6. The correspondence is then threaded onto themetal binding tape. The leaves 6 and 7 are next hinged upwardly into aparallel position approximately at right angles to the cover 2. The endsof the tape 9 are then passed into the respective incuts l3 and recesses141- and are then turned either inwardly or outwardly dependent upon theposition of the iecesses, down upon the reinforcement 12. The lockingplate 16 is finally engaged with the reinforcement 12 and sprung intoposition.

The papers and the binding tape are thereby securely held in position.If a pa per is to be removed or fresh matter placed upon the file theoperation is reversed, the fresh matter added and the file againoperated as described.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. A file for correspondence and the likecomprising a cover having opposite leaves or wings, a binding tapeattached to one leaf, and a metal reinforcement attached to the otherleaf and having incuts therein to receive the binding tape, incombination with a substantially U-shaped locking plate pivoted at oneend thereof to one of the leaves for swinging movement into posit-ion tostraddle the reinforcement and lock the ends of the binding tape inposition.

2. A file for correspondence and the like comprising a cover havingopposite leaves or wings, a binding tape attached to one leaf, and ametal reinforcement attached to the other leaf and having incuts thereinto receive the binding tape, in combination with a substantiallyU-shaped locking plate pivoted at one end thereof to the reinforcementfor swinging movement into position to straddle the reinforcement andlock the ends of the binding tape in position.

3. A file for correspondence and the like comprising a cover havingopposite leaves or wings, a binding tape, and a metal reinforcementhaving incuts therein to receive the binding tape, in combination with asubstantially U-shaped locking plate pivotally secured at one end to oneof the leaves, said locking plate having converging sides or legsadapted to engage the reinforcement and lock the ends of the bindingtape in position.

4. A file for correspondence and the like comprising a cover havingopposite leaves or wings, a binding tape, and a metal min forcementhaving incuts therein to receive the binding tape, in combination with asub stantially U-shaped locking plate pivotally secured at one end toone of the leaves, said locking plate having converging sides or legsadapted to engage the reinforcement and lock the ends of the bindingtape in position, said sides or legs having flared edges to facilitatethe entrance of the reinforcement.

5. A file for correspondence and the like comprising a cover havingopposite leaves or wings, a binding tape, and a metal reinforcementhaving incuts therein to receive the binding tape, in combination with asubstantially U-shaped locking plate pivotally secured at one end to oneof the leaves, said locking plate being adapted to engage thereinforcement and lock the ends of the binding tape in position, andsaid reinforcement having catches to fasten the locking plate to thereinforcement when engaged therewith.

6. A file for correspondence and the like comprising a cover havingopposite leaves or wings, a binding tape, and a metal reinforcementhaving incuts therein to receive the binding tape, in combination with asub stantially U-shaped locking plate pivotally secured at one end toone of the leaves, said locking plate being adapted to engage thereinforcement and lock the ends of the binding tape in position, saidlocking plate and reinforcement constituting companion elements, one ofwhich has catches whereby the locking plate is fastened to thereinforce- 105 ment when engaged therewith.
